Perioral dermatitis is a skin condition that is most prevalent in women, according to the American Academy of Dermatology. The term "perioral" refers to the area around your mouth; dermatitis means an inflammation of the skin. Perioral dermatitis displays itself as red, itchy, painful, acne-like bumps around your mouth. The facial rash can be short-lived or a more chronic condition; each person's body responds differently to the inflammation. Medical researchers have yet to pinpoint an exact cause of this form of dermatitis, but according to the American Osteopathic College of Dermatology, risk factors and possible causes include the use of steroid medications, overuse of facial cosmetics and even an allergic reaction to certain kinds of toothpaste.
Steroid Use
One of the most likely and more frequent causes of perioral dermatitis, according to the New Zealand Dermatological Society, is using topical steroids on your face. Corticosteroid drugs are anti-inflammatory medications and can be used to treat a variety of skin conditions, including psoriasis, eczema and rosacea. It is somewhat ironic then, that prolonged steroid use can cause a different sort of skin rash. Inhaled steroids that you may have taken through your mouth or nose to treat respiratory illness may also increase your risk of developing perioral dermatitis. If you have been prescribed any form of steroid medicine and experience an angry, red rash around your mouth, contact your doctor for further instructions.
Heavy Cosmetic Use
The New Zealand Dermatological Society's information service Dermnet NZ explains that using copious amounts of facial products such as creams, makeup and moisturizing lotions could lead to perioral dermatitis. Research reported by Dermnet NZ theorizes that the characteristic rash may be caused by bacterial or yeast infections that invade the hair follicles on your face. Heavy use of cosmetics can clog your pores, creating inflammation and possible infection in the hair follicles. Washing your face with water while the rash is present may help calm the irritation.
Allergic Reaction to Toothpaste
Some people may develop perioral dermatitis as an allergic reaction to the toothpaste they are using. The American Osteopathic College of Dermatology explains that toothpaste that contains fluoride may be the culprit in some cases of the facial rash. Discuss your symptoms--the appearance and timing of the rash--with your physician to determine if your dental care products are causing your discomfort.
